In propositional logic and Boolean algebra, De Morgan's laws, also known as De Morgan's theorem, are a pair of transformation rules that are both valid rules of inference. They are named after Augustus De Morgan, a 19th-century British mathematician. The rules allow the expression of conjunctions … See more The negation of conjunction rule may be written in sequent notation: $${\displaystyle \neg (P\land Q)\vdash (\neg P\lor \neg Q)}$$, and See more De Morgan's theorem may be applied to the negation of a disjunction or the negation of a conjunction in all or part of a formula. Negation of a disjunction In the case of its … See more In extensions of classical propositional logic, the duality still holds (that is, to any logical operator one can always find its dual), since in the presence of the identities governing … See more De Morgan's laws are widely used in computer engineering and digital logic for the purpose of simplifying circuit designs. See more The laws are named after Augustus De Morgan (1806–1871), who introduced a formal version of the laws to classical propositional logic. De Morgan's formulation was … See more Here we use $${\displaystyle A^{\complement }}$$to denote the complement of A. The proof that Part 1 See more Three out of the four implications of de Morgan's laws hold in intuitionistic logic.
